Fix GDB crash with upstream GCC due to memcpy(NULL, ...)
Similar to qsort(), the glibc version of memcpy() also declares its
arguments with __attribute__(__nonnull__(...)). If NULL is passed
anyway, upstream GCC's new pass '-fisolate-erroneous-paths' typically
causes a trap in such cases. I've encountered this with GDB in
chain_candidate() when trying to execute the break.exp test case.

* dwarf2loc.c (chain_candidate): Prevent invoking memcpy with
NULL.
